I am opening a wizard from an E3 plugin that then opens a handler in an E4 plugin. During the processing of the dialog, the windows is somehow detached from the model. 

As can be seen below, the E3 part of the stack opened a wizard dialog which I believe causes the window the be disconnected somehow.


java.lang.IllegalStateException:
 Application does not have an active window
